标准编号：ISO 3231:1993

中文名称：色漆和清漆.耐含二氧化硫潮湿空气的测定

英文名称：Paints and varnishes — Determination of resistance to humid atmospheres containing sulfur dioxide

发布日期：1993-01

标准范围

规定程序的原理是将涂层试板暴露在含有二氧化硫的规定潮湿环境中。对于厚度不超过约40μm的涂层，通常建议在大气压下测量0.2升的体积。暴露的影响由相关方事先商定的标准进行评估，这些标准通常是主观的。适用于单层漆膜或多层涂料系统。

The principle of the procedure specified is to expose a coated test panel to specified humid atmospheres containing sulfur dioxide. A volume of 0,2 litre, measured at atmospheric pressure, is generally recommended for testing coatings of thickness not exceeding approximately 40 μm. The effects of exposure are evaluated by criteria agreed in advance between the interested parties, these criteria being usually of a subjective nature. Applies to single-coat film or a multi-coat system of paints.
